Be it known that we, HERMAN BESSER and J1 1ss19 H. BESSER, residents of the city of Alpena, in the councy 0'E Alpena ancl State oi M.ichigan, and citizens 025 the United. f5tates of Ameriea, have: invented oertain new and useful lmprovements in Mo1d Boxes, of Which the .following is a specifr cation.

Our invention relates to new und. improved molds -i"or 'inolding b1ocks o1 othex cemenyt 01 concrete products for'building 01' other purposes of. solid er hollow form and of yectangular 01 other quadrilateml shape in general, one that may be locked in closed relation for receiving the cement material and which may be readily und quickly 1e leased without injuring the produet, leaving the sides, ends and eorne'rs Perfeet und one which Will furn-ish 21 perfectly sqilared" openingg; in the mold when its Parts 211e olosed und the nature oiiteconstruction fends 'o positively keep tl1e Same in proper 'adjustment.

113 is a specia1 objeot of 0111 invention to provide o. mold box thnt shall comprise sides und ende, the former pivoted to a common framework at ihe .iG5L1 oft the end plate and also having the freut ehd ph1te pivotecl t0 a. sido plete appreciably back of the fronc end oE the same, io1 a purpose to be fully em loined.

lt i.s a further object of omainvention to provide a mo1d box in which the front end p1ate serves tfu1rther es a 1ock elenxent-itor the sides o;f tho mo]d and also es zu 1neans tio1: nmnnally lifting the side -to Which it pivoted; and in whieh the latch member is carried. by uhe other side plate anc1 also serves es the means for liftingg; that side, so that the locking elements for the de vice pro vide manual .meens for lifting readily the entire rt'ront end. of the niold after the side plates have been soparaytedl I.t is also an object olf ein; new construction tzo provide especially streng side plates withoui; using truss elements, andwithout addin irengthening menfibers that Will be cumbersomein themselves or in combination vith the plates with Which they zue used, in fach, fh'e strengthenina ba1s we use for these side plates serve an additional purpose other thaa1 that oi melr.ing the plates more rigid, will appear from onr desycription DOW to be given.

7It is a, fo.1. the1r objecia co provide the side 1923. eria-zl N0. 638,602.

p1aces of our new mo1d of greater width than ehe end plates so that they n1ay serve as a hopper to properly direct the 1naterial into the mold when the( parts are closed, the edges of these plates forming a fo1 directing; the movement 01 the strike-off tool, though the latter is so conscructed that it trowels ofl the material at'the 1evel of the end plates.

"Further objects and advantages Will appear in the' following cle scription it heilig onerstoo that various changes in form zu1d minol detzlils of construction may be resort-(ad to wiijhin the scope of the appended claims.

VJo ottain these objects in the following manner, reference being 1nade to the acoonipanying drawings, in whioh:-

Figure 1 is 21 perspecitive view 0f our mold box;

Figure 2 is a plan view of the same with the parts swung open;

Figure 3 is a perspective of the pivoted end gute in its elosed relation wish the side plate the latch being unlatched, and

Figure 41- is a perspective 0f the end gace shown pivoted to the front ortion 0f one. o1 the side plates.

Referring DOW to the drawings in detail,

our mold b0x comprises two side plates A end B.n 17eor end plate C and tue front p'iate D, the 1atter part forming an integral portwn of the look1np; mechan1sm [01 the entire unit, es Will belater explained. The

side plefces have fixed to their lateral edges flanged bare 10, Lshaped 111 cross section, the

vertijcal flanges beim; riveted to the plates so filmt the horizontal flanoges are flush wit-h the edgzes of the plates, these bare 10 serving to positively strengthen the plates A 2u1d B, to affford horizontal flange strips for attachment of oft-her memoels, and when extended roarwardly beyond the end place C, es later explmned, afliording piVot poinfos at -vor? advantagcous d-iStences from the platt;

O. Bars 10 are extended at 11 a'nd pivoted et 12 to a, cross bzw: 1;3 while the correspond- .ing 1ower bi1rs 14 are extended 're211wardly of the ame length es. 13, both beir'1ggirefeh ab1y iOrmed of L striPs f01 great strength and ease in attachinp; other elements.
